TYIPE OR MATRIX.

Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed. April 7, 1914. swarm. 830,115.

To all whom it may concern:

Be it known that I, ALFRED W. F. GUEST, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type or Matrices, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to type or matrices for typographical machines, such as linotype machines of the generalorganization represented in Letters Patent of the United States, No. 36,532 to O. Mergenthaler. In machines of this class, the matrices are stored in a magazine, are released therefrom by the manipulation of the keyboard mechanism, are assembled in line and then presented to a mold, wherein the slug or linotype is cast. After this, the matrices are distributed and restored to the magazine from which they started.

In the ordinary form, the matrix is pro vided at its upper end with a single pair of edgewise-projecting ears whereby it is sustained at times in its passage through the machine, and at its lower end with similarly projecting ears, whereby it is alined with reference to the mold. As the upper ears are not always located directly above the center of gravity, but are frequently at one side of the matrix, there is a tendency for it to pivot or swing, and this tendency isemphasized and increased in the case of the thicker matrices.

'My improvement consists specifically in the formation of the matrix with a plu rality of sets of ears, which are preferably situated in difi'erent vertical planes and on opposite sides of its longitudinal median lme. This construction secures the suport of the matrix at a plurality of pointsin its thickness durin circulation, and

. similarly provides it with a plurality of -tions may be made therein, and in the mode of application, which will still be comprised within its spirit. Similarly,.the invention may be adapted to type or dies, as well as to matrices. "Generally speaking, I

desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claims.

Referring to the drawings: Figure 1 is a perspective view of the improved matrix; Fig. 2 is a bottom view of the same; Fig. 3 shows the first and second elevators in 00- operative relation; Fig. 4 is an enlarged detail thereof; Fig. 5 is a detail of the first elevator and right-hand vise jaw in the ordinary operation and showing the use of matrices of usual form; Fig. 6 is an elevation, partly broken away, of the distributer, channel entrance, magazine, etc.; and Fig. 7 illustrates a modified form of matrix.

The matrix X (Figs. 1 and 2) is of the large or display variety, and is formed with two pairs of upper ears X and X and similarly two pairs of lower ears Y and Y It will be noted that the ears X and Y are in one vertical plane, and the ears X and Y in a different vertical plane, located respectively at opposite sides of the median line of the matrix. In this way, during its circulation through the machine, the matrix always engages the several sup.- porting members at a plurality of points in its thickness, and thereby its constant vertical position is assured. The desirability of this construction and mode of operation is illustrated graphically in the drawings. For instance, in Figs. 3 and 4, the assembled line is shown in course of transfer from the first elevator A to the second elevator B, at which time it is necessary that the matrices be maintained in vertical position. If they should swing or tilt during the transfer there would be-a liability to a -trices W formed in the customary manner with a single pair of ears W at one side thereof. the swinging or tilting thuspermitted being apt to throw the. matrices out of line and even into position to collide with the jaw.

Fig. 6 illustrates the adaptability of my improved matrix to the ordinary magazine.

The matrices X pass from the distributing mechanism G through the channel entrance E into the magazine F formed with the usual grooves F to engage the matrix ears. It will be noted that these grooves are located in the ordinary proximity to each other, or in other words, so as to receive the regular matrices side by side therein. However, it will be seenthat due to the present formation of the matrix X, with ears in difierent vertical planes and separated from each other, the ears X and Y will enter one pair of grooves F and the ears X and Y will enter the adjoining pair of grooves. In other words, there is no necessity for a change of magazine to permit the employment ofthe thicker or displa matrices. It will also be noted that the employment of two lower ears Y and Y enables the matrix to engage simultaneously at different points in its thickness during alinement with reference to the mold, and thereby lessens'the liability to twisting or distortion.

In Fig. 7 I have shown a modified form of matrix, wherein one of the lower pairs of ears is omitted, but still provided with two pairs of upper ears. i

As previously stated, I have shown my invention only in preferred form and by Way of example, and in a special form of application, but obviously many other modifications and alterations therein, and in its mode of adaptation, will suggest themselves to those skilled inthe art, without departure from its scope.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States, is as follows:

1. A type or matrix formed with a pluralityof simultaneously-active sets of supporting ears.

2. A type or matrix formed with aplurality of simultaneously-active sets of supporting .ears l cated in different vertical planes.

3. A type or matrix formed with two sets .of supporting ears located setwise on opposite sides of its longitudinal median line.

4. A type or matrix adapted for circulation'in'a typographical machine and pro vided with means to support. it at a plurality of points setwise thereof duringcirculation.

5. type or matrix adapted for circula- I tion in a typographical machine and provided with means to support it setwise at opposite sides of its longitudinal median line during circulation.

6. A type or matrix formed on one of its edges with two simultaneously-active supporting ears located wholly in difierent vertical planes. i p

7, A type or matrix formed on one of its edges and at its upper end with two supporting ears located in diflerent vertical planes.

(8. A type or matrix formed on each of its vertical edges with two simultaneouslyactive supporting ears located wholly in different vertical planes.

9. A type or matrix formed on each of its vertical edges and at its upper end with two supporting ears located in different vertical planes.

10.- A type or matrix formed with a plurality of simultaneously-active surfaces to 12. A type or matrix formed on one of its edges with a plurality of ears to aline it with I reference to a mold, the said ears being located in diiferent vertical planes.

13. A type or matrix formed with a plurality of sets of guiding ears, the said sets being located in different vertical planes and each comprising two ears located oneach of the vertical edges of the type or matrix.

'14. A type or matrix formed on each of its opposite edges with two ears, the ears on each edge being located in the same vertical plane but in a diflerent vertical plane from those on the opposite edge.

15. A type or matrix adapted'for circulation in a typographical machine and provided setwise at one side of its longitudinal median line with supporting ears, the said matrix being provided with additional means to support it at the opposite sideof its longitudinal median line so as to main tain it in a truly vertical position during C11- culation.
